Rare black Victoria Stone, or Imori Stone, oval cabochon with eye catching patterns splashing across the face of this cabochon as it changes direction. Light changing fans appear and disappear as you change the direction of this stone in the light. The cabochon is polished on both sides in preparation for any open settings. The top is domed all the way to the bottom and is flat on the bottom - ready for smithing, wrapping or setting.
This stone is 9.1 grams (45.5 carats) and measures 38 mm x 30 mm x 4 mm. Victoria Stone has a hardness of 6.
Victoria Stone (some call it Imori Stone) was created in Japan by Dr. Imori and family from the 1960's to 1990's. The stone is man-made in a sense due to Dr. Imori had a process known only to his family of mixing minerals in a lengthy process to render this gem, similar to Nephrite Jade. Therefore, the stone is a laboratory produced stone from natural raw materials, which include feldspar, quartz, magnesite, calcite, fluorspar and others. A total of seven different minerals combined under high pressure and temperature. The cooling process is the key to producing the 'fan' patterns. The unfortunate result is Dr. Imori passed away and his son continued the process until the 1990's when the production shut down. Others have tried to recreate the process but have not been able to duplicate the it so the only available Victoria stone is what is left in old collections and is non-replenishable - so, when it's gone, there is no more.
